Don't ever listen to a wood seller tell you, "the one I am selling will be OK for thru bolt guns but not for doubles".
Does the hole down the middle somehow make the wood stock stronger?
(I know, you are an engineer and your book says...)
Thru-bolt gun stocks break easier than any other. Stocks don't break from recoil, they break from dropping. A genuinely sound piece of advise would be, "Don't drop your gun with a thru-bolt stock as it will break easier than your double gun stock. But please don't drop that one either."
<For anyone that doesn't have it, I will send my book Fine Gunmaking: Double Shotguns with Chapter 1 titled "Good Wood" (a truly comprehensive treatice on selecting a blank for a shotgun stock) For $25 +5 postage.
Please PM for the book before you buy any gunstock blank.>
